Safari Tells Me I Need to Update Flash Even Though I Just Did

Safari and Firefox were both telling me while using YouTube that I needed to upgrade my version of Flash. So I upgraded and now Firefox no longer gives me the upgrade message, but Safari still gives me the following message: "Upgrade to the latest Flash Player for improved playback performance. Upgradenow ormore info."

The part that looks empty says "Upgrade now or more info" with two links in the original. (I tried changing the font color to make them visible but obviously it didn't work. 😮
